Can the AIDS police station check many grades?

The AIDS police station can check at multiple levels. The police station can retrieve it, but only if the information retrieved is relevant to the case. If it has nothing to do with the case, the police station cannot view other people's private information. After retrieval, it can only be used in the case, not for other purposes, and personal privacy information cannot be publicly released. It is necessary to control the scope of knowledge and ensure the legitimate rights and interests of the parties.
